India’s market regulator, Securities and Exchange Board of India (SEBI), has initiated a significant regulatory action alleging violations of insider trading norms by several current and former senior officials associated with PwC and EY’s Indian entities. The case relates to a major Yes Bank share sale in 2022, according to details contained in a regulatory notice reviewed by Reuters.
According to the regulator, senior executives linked to US-based private equity firms Carlyle Group and Advent International are also under the scanner for allegedly sharing unpublished price sensitive information (UPSI), an act prohibited under Indian securities laws governing insider trading.

What SEBI Has Alleged
SEBI’s show-cause notice reportedly names 19 individuals for alleged violations of insider trading regulations. Of these, seven individuals are accused of trading securities based on UPSI, while four are alleged to have shared such information with others. In addition, the regulator has raised concerns about weak internal compliance systems involving eight senior officials from PwC and EY.
The notice suggests that during the preparatory phase of the Yes Bank transaction, sensitive information may have circulated beyond authorised channels, enabling select individuals to trade ahead of the public disclosure of the deal.
Role of Advisory and Valuation Mandates
The regulator’s findings indicate that Advent International had appointed Ernst & Young (EY) to provide tax advisory services prior to the share sale and sought feedback related to Yes Bank’s management. Separately, Yes Bank engaged EY Merchant Banking Services for valuation-related work connected to the transaction.
SEBI believes that it was during these advisory and valuation processes that UPSI may have been exchanged improperly, breaching confidentiality norms and insider trading regulations.
The 2022 Yes Bank Share Sale
The case centres on a transaction completed in July 2022, when Carlyle and Advent jointly acquired approximately 10% equity stake in Yes Bank for around $1.1 billion. The deal was publicly announced on July 28, 2022, and the following day, Yes Bank shares surged nearly 6%, reflecting strong market reaction.
According to SEBI, unusual trading activity in the bank’s shares prior to the public announcement triggered regulatory scrutiny, prompting a detailed investigation into trading patterns, communication trails and advisory roles linked to the transaction.
Notice Not Public, Responses Being Prepared
The show-cause notice issued by SEBI has not been made public and had not been previously reported. Sources familiar with the matter said the individuals and entities named in the notice are currently preparing their responses to the regulator. Given the sensitivity of the ongoing investigation, the sources declined to be identified.
So far, Carlyle, Advent, EY, PwC, Yes Bank and SEBI have not issued any official statements in response to queries related to the allegations.
Possible Regulatory Consequences
Market experts note that a show-cause notice represents the first formal step in SEBI’s enforcement process following an investigation. If the allegations are upheld, the regulator is empowered to impose substantial monetary penalties, enforce market bans, or initiate other disciplinary measures under Indian securities law.
The case is considered particularly significant as it involves global consulting firms and private equity players, and pertains to a high-profile capital market transaction—making such enforcement action relatively rare in India’s regulatory landscape.
Implications for the Market
Analysts believe the case comes at a time when India’s capital markets are witnessing increased deal activity and heightened global investor interest. Against this backdrop, SEBI’s action is being viewed as a strong signal of its intent to reinforce transparency, accountability and market integrity.
In recent years, the regulator has intensified its crackdown on insider trading and market manipulation. In a separate case, SEBI had also alleged violations by the Indian unit of Bank of America during a fundraising exercise.
What Lies Ahead
All eyes are now on how the accused parties respond to SEBI’s notice and whether the regulator proceeds with penalties or further enforcement actions. The outcome of this case could play a pivotal role in shaping future standards around information sharing, advisory conduct and compliance obligations in India’s capital markets.
As the regulatory process unfolds, the case is expected to set important precedents for consulting firms, banks and global investors operating in India’s rapidly expanding financial ecosystem.
